Beit known that I, O'r'io .,'My invention although applicable to any shaft required to, be rotated by manual artieularly adaptable to the operating sha t ofthe hand brake mechanism lof railway cars, and it has for its object to ro-r vide a device of thisA nature -whiehwi in itself present both the means wherebytlie hand power can be applied and the abutment from 'which the the necessit i of t e operator depending upon his f oot :hol for the piiriose, such abutment. 2o.* serving also as a means i `or looking the shaft against retrogression.

The invention may sistV of the combination and arrangement of l arts hereinafter described and pointed, out.

'straps u ressure is derived, without view ` "PatenteilNovL 10, 19081v y Vthe shaft o can 'be hield against rotation in one direction. The means .forv rotating the shaft in t'l'ie o posits direction consists of a s'panner n an a poonall portion o of. the 1 shaft; the Spanner being formed'with a pair of trunnions upon its opposite sides and presenting ovalieads 1 prefer-ably gpar'allel to the body of the span-'- neri These trunni'ons bear in dia onal-slots in the upwardly turned ends t o a pair of and c conjoiiitly. encircling a flanged collar Iw keyed to the shaft, while the strap u is' forrned witha lip :c and a tubular stud 'yj with diminished or contracted' end z, and the strap tu lia's a transverse slot 2 to receive the lip a: and a hole 4 for the diminished end of the stud y. These parts are secured together.

.e in the form of .a stra i encircling the-flanged collar. by inserting t e-lip :t into the slot'2 'and thediminished end z of the stud y into x the hole 4 and expanding the protruding endofz, tlius obvia'ting tlieiiecessity of a a piece at this point,1 although a hole gthroug i the strap u in line ,witlivthe stiidfy y'enablesva bolt a'iid'iiut to be' Vused in 'the event of the stud being broken off.. The oval heads 7 and diagonal slots s 'en able the Spanner to be readily set in place fore the straps are'fastenedA-together, land lshould one of the upt'urnedpstrap 'ends `be broken' off the sp ann er will still be retained in position by the remaining stra end. i

OperationzN-*The operation o tur'ningltihe, shaft by'xnyimproved rotatin ear is as1 followsz-The operator takes hed of. the s lanner with one hand and the handle k of tlie' p awl`with the O'tlieifj andA he pushes against the pawl while he pulls upon the Spanner thus obtaining hispiirchase or abutment, (through the pawl and ratchetwheel) in the shaft, and as he disengages the sp'anner and returns the same, by his right hand,

for a new operation,

against retrograde rotation with his left-- hand. i

What I claim islas follows he retains *the* shaft A 1. lThe conibinationrwith a shaft to be rol tated and manually operated means fori'o'- tating thel saine, of means for preventing'ret rograde rotation of the shaft 'during the insenting a hand-hold whereby the operator .can obtain the necessary purchase to enable him to operate thc said first mentioned means.

2. The combination witlra shaft to be ro- 'terinissins, such last mentioned means pre tated, a stationary part adjacent thereto and manually operated means for rotating the same, of a 4ratchet .wheel 'mounted rigidly' upon the shaftLand a pawl pivotally connecter to the stationary part and adapted to enage the ratchet wheel, such pawl having4 a and-hold formed integrally therewith and furnishing the necessary purchase .to enable an operator to operate the said first mentioned means.'

3.- 'lhe combination `with a shaft to'be ro'- tated, a stationary part adjacent thereto and manually operated means for rotating the same, of a ratchet Wheel mounted rigidly upon the shaft, and a pawl of box-form pivotally connected to the stationary part and inclosing and ada ted to engage the ratchet whleel, such pawl being formed with a handho d,

4. The combination with 'a shaft to be rotated presenting a polygonal portion, of

means for intermittently rotating the vsaine comprising a Spanner adapted to engage such polygonal portion, a device rotatably mounted upon the shaft and presentingl a projecting portion adapted to rotatably s'up ort the Spanner out of engagement with tllie shaft, and means formed partiallylon the vsaid device and partiallyon the Spanner for reventing the disconnectionof the Spanner rom the said device except in one angular osition.

5.' The combination with a sha t to be-roated presenting a' polygonal portion, of-

means for intermittently rotating the 'same comprising a sp annex' adapted to .engage such l polygonal portion, adevice rotatably mounted upon the shaftand presenting 'a projecting portion Witha diagonal slot and adapted to soaaoi rotatably su port the Spanner outiof engagement with t ie shaft and a trunnion with an oval head formed on the Spanner and engaging in the slot for preventing the disconnec' eans for maniially rotatt rotgin'g device, a two piece strap for carrying means for manually rotating the shaft, such strap pieces being formed l -at'one end to interlock, and one of the pieces being formed with a tubular stud with one end diminished, and the other. with a hole to receive the said diminished end and .have the sameexpanded therein. 8. ln a shaft rotating device, a two piece strap forv carrying means for manually rotating the shaft, suchV strap pieces being formed at one end to interlock, and one of the pieces being formed with a hole and atubular stud concentric with.such hole and having one end diminished and the other with a hole to re-v ceive the said diminished end and have the saine expanded therein.

In testimony whereof, I have signed-myA name to this specification, in the presence of two 'subscribing Witnesses.
